Description
The AP4570 offers two modes
of operation - Track & Hold
and Track & Peak-Hold. In
"Track & Hold"
operation the output tracks
the input signal. When an external
contact is closed, the input
level is "saved" and
its corresponding output signal
is held indefinitely until the
contact is opened. Releasing
the hold switch (pins 8 and
11) allows the output to again
follow the input. The "Track
& Peak- Hold" mode
is similar to "Track &
Hold" operation except
upon contact closure (pins 8
and 11) the highest input is
"saved" and the corresponding
output is held until a higher
signal level occurs.

Application
Model AP4570 is useful in capturing
DC-input signals to be held
for further processing or signal-conditioning.
Typical applications include
monitoring peak electrical or
energy demands, capturing process
conditions such as flow rates,
equipment protection and taring
to factor out unwanted dead
weight.
